You're a smart man. I think that's what drew me to your channel a couple of years ago. That, and your sparkling personality! (Oh, and buckle your seatbelt, 😆).

Unfortunately with transmission it can be a multitude of things. Best bet is to do a thorough diagnostic on it and go from there. Most would recommend the fuse because it's cheapest route, and solenoids fairly cheap as well. Save the headache and completely diagnose it.

Chevy Gmc notorious for trans sticking check your accelerator pedal position sensor

When I buy replacement fuses I always choose the ones with an led wired across in parallel with the fuse, that way when ones blows it lights up so you can locate it easily

I have an 02 trailblazer that is having the same issue. Shifting into 2nd just fine then hard time shifting into 3rd if it does at all. Any advice?

Going from park to drive is your first shift. As you accelerate and it shifts again for the first time while moving forward, you're actually entering second gear. gotta count your first rolling shift and second gear.

Purchase a good scanner so you can see the solenoid active positions and trouble shoot it right. Get diagrams and check powers and Grounds. Don't guess, test!

This is what has happened to my just installed remanufactured Trans. First the check engine for no reason and the the trans was only pulling in second.

I'm having the same problem but if I put it in tow haul it seems to shift fine

You didn’t do a thing to it and it started working ?

How did you know you needed to change the 10A BTSI?

Mine wont go into highest gear. ?

I bought a Remain transmission For 7 year warranty . I had 257000 miles before I replaced mines I'm still having this problem that you experience and that in mind is the 5.3 I took it the one transmission shop they couldn't figure it out they said it's not my transmission what's up top mission which I told him and I knew it wasn't because It was brand new. And my truck is throwing all types of transmission codes. So hopefully you find A good shop

I had mine on the obd2 and it said the torque converter is slipping.

Change of transmission strainer and new transmission fluid and you should be good to go

Replace all 4 shift solenoids! Drop the pan!

Had the same problem was about to pull the transmission then saw a video telling that the TPS (throttle position sensor) might be bad. $15 part and it shifts!

Mine is doing the same thinngggg 🙄 gm needs to do better I did everything on my damn truck and nothinnnnn😤 hopefully I can figure it out!!!

You should have to tear down your transmission, change the 3/4 clutch pack with the pistons, have to pressure test the passage with air for the input drum for air leakage between the drum and shaft

Transmission shift solenoids my car was doing that too

Your truck intermediate shaft ion your steering column is worn and replacing. that’s what you hear that clunking in the your steering. Common on those years

mine shifts into 2nd i think then after 60 it forces itself to go went to a mechanic said he need a new transmission 😕 someone help not tryna drop a bag

The transmission is in limp mode check for power at the plug should be a light pink wire if you have power at the plug than its going to be in the transmission pan ethier bad harness or 1-2 shift solenoids

What was the issue. Mines doing the same and I can't find any awnsers

Mine does the very same thing! When it's cold, I don't have a problem, until it warms up good. (COIL?)

Try to change shift solenoids.

i have same or similar issue with shifting in 4l60e. I can get it to shift by applying more or less throttle to about 3300 rpm which i believe is what happened when yours suddenly worked.. no downshifts though i have to manually downshift back to 1st and adjust throttle at each shift to get it to grab. no overdrive. could VVT solenoid cause this?

What was it?

I changed all the fuses and sensors but still won't shift into reverse and moves forward when in neutral

Try changing the b solenoid in the transmission, they cost about $20-26 a piece. I always change the a and b shift solenoids shake your old ones make sure the rattle. Take a small pick and a zip tie and work the shift valves out one at a time spray cleaner or gas in a squirt bottle and clean the ports and valves off good blow air to finish cleaning them. Dip valves in clean trans fluid and reinstall oil solenoid seal before installing, test drive if that doesn't fix it remove the heatsheild from the passenger side of trans Look for the 1-4 shift servo above the pan and between the electrical plug and arch of bell housing about 3" around. Clean and brush around the inner cap. Push in on the center with a pry bar and insert a screwdriver onto slots and pry out retaining ring clean area and blow clean inner surface where ring was, let off pressure with prybar Use channel lock pliers twist and pull servo cap out watch for inner piston to fall out remove the rest of servo spring and ban apply pin. Notice how sloppy the pistons all move around each other replace with new not remanufactured, oil new one with trans fluid and maybe a little vaseline around the cap seal and trans case reinstall drive it. Make sure your computer isnt the one that loses computer shift ground if so install jumper wire then test drive. Check and clear codes if it has code p0758 p0601-p0605 replace the computer

My 02 (4l80 swapped) truck is doing this randomly Trans was fully rebuilt and working swapped the motor out an now I have no 3rd/4th Plugged in HP tuners An it says I’m going through all gears But it doesn’t physically shift I tried to “command” shift through HP tuners still no response Did a ohms test at the plug I have 12v(e) 20.1ohms on (a) an 418 ohms on (b) Guessing there’s a short in the internal harness?? No codes tho Replaced tps an speed sensor Checked every fuse on the truck (none blown) So frustrating

I have a reman transmission in now. And still having the same shift problems. I replaced speed, troque, and shift solenoids. Not to mention the Tccm. Transfercase control module. Still hasn't fixed the problem. Im at a loss now too.

Maybe it can be not the speed sensor but the harness that runs from the speed sensor to the transmission check your harnesses people it might save you a shiet ton

Any fix?? Having the same issue :(((

Having the same problem just changed trans and still doing the same..have any ideas yet?

I got an 2011 1500 Silverado with the same problem what would the cause of it be?

Not exactly the same but on my truck, 2000 Chevy 2500, 6.0, the PRND display was all messed up and the trans was wonky. I replaced the PRND switch and all was well again. Also you are getting an evap code check the fuel tank vent valve, they are notorious for going bad. Now your air bag light...sorry, no idea, but would be curious what the problem is if you fix it.

Did you ever figure this out? I have an issue similar to this, Mines on a 11 Yukon Denali, just got a jasper reman transmission put in bc the old one went out and we have about 600 miles on it and it hard downshifted into first or second and revved out, then when we got on the gas it would just rev out and not shift up past 2nd, later trying to limp it to a shop I figured out of I let it coast about the time it was supposed to shift to 3rd it would go in and drive and shift great until I came to a stop again, fluid looks good and was still full and there was no “burnt” smell, we have a 3yr/ 100k warranty but the installer basically is trying to pass the hat, said it’s not the transmission bc it’s a jasper, so we are waiting to see what this other trans shop says, just trying to do some research of my own to see if I can figure out the cause

Mine acted the exact same way. It was the throttle positioning sensor (TPS). I bet it idles high after driving a bit and you put it in park. I was even throwing an evap code. 50 dollar part and two screws

So i have a 2005 5.3 l silverado an nutrual acts like drive and i dint have a reverse do you know why?

Replace your solenoid in the transmission. Easy fix. Drop guh our pan, pull your filter. You should have 2 solenoids side by side. May as well change them both while your in there. Online they cost about $13 advance had them in stock for $23. Change your filter while you got it off. Good luck!

You start in first. So when it shifts the first time That’s not first it would be second

Third and fourth clutch pack

Having this problem right now did u find the problem?

Did you see if your o2 sensor and cats are good that what is going on with my truck right now

It always starts in 1st gear and it shifts into 2nd and so on. Try changing the fluid and filter if that doesn't fix it then change the shift solenoids

2005 yukon same vs anyone figure this out yet?

You are in FIRST gear when you pull out!

This is the very problem my husbands truck has .. he has a rebuilt transmission an when it shifts to second it won’t shift to 3rd or 4th just reves up

Dude lol when you start moving, its in first gear already. It doesnt shift into 1st your first shift is 2nd.

The ball in the valve body closest to the bell housing will get stuck and cause this problem. Separator plate replacement and or neoprene ball replaced in that area of the plate,first flatten out the edges of the hole with a light hammer.

scan tool?

Sometime the Corvette servo,

My 04 silverado has the exact same problem I had change the solenoids yesterday and new filter and trans fluid still have the same problem haven't checked the fuse though can it be the 1 2 shift accumulator ?

Find you a transmission shop or rebuild it yourself, it’s time

I'm having same problem. Been thru 2 Trans and 2 pcm

I had the same problem mine was the bottom that shows 2 w 4wf 4wb Mine was on 4wb i change to 4 wd auto that took care off it good luck it work for me

More than likely it’s the 3-4 clutch plate and honestly it would be easier to just buy a new trans

I have a 2004 silverado 1500 that shifts to second gear in high rpms. The crazy thing is the truck only has 38000 miles. It's like new Inside and out. So it's not ware. It did it once around 4 years ago, and didn't start up again until this week. 09/28/22

i would guess its the 2-3 shift solenoid

Did u ever figure out what the problem was

Can anybody tell me why I can manually shift into 1st an 2nd but drive an 3rd it feels like it wants to shift but it just stays in 2nd. It was sitting for a while, and before it felt like a neutral but all sudden, it actually does something just not shifting.

Apparently it can be the 10 amp fuse inside the truck

Oh reset the solenoids after you change them.

Did you figure out what the problem was mine is doing the same thing

The the fuses in the door.

My transmission slips from 2 to 3 and drive

Lol it starts in 1st

My jeep don’t shift at all lol idk what’s going on either

It’s only in 2nd not going into 3rd

Its not going into 3rd

You are in 1st gear when you pull out then it should go to 2nd

What was the issue? Having same issue not shifting into 3rd or 4th. When I manually put it in 1st and 2nd no problem. But on Drive it doesn’t go anywhere.

Ignition switch

That fuse wasnt blown, have you checked trans fluid level?

Check speed sensor

Mind started the same thing 04 avalanche

Well I'm looking at your tag and looking at your speedometer your tax showed that it was shifting in each gear don't know what else to say then you should look closer just shifts real easy.

Bro I just started having this problem with my 04 Chevy Silverado 1500 4.8 was driving it then it sounded like something fell out of the transmission an I went from 3rd to first quick now it won’t go past 2nd gear still parks, reverse, goes into neutral. Fixing to drop the pan an change the fluid it’s black and thinking About getting the grand master solenoid kit an for some reason it won’t let my scanner read the codes I just wanna make sure I’m going on the right path or if it’s even worth it plus car payment suck especially after u haven’t had one in 4 years lol

gear shift solenoid.

Its not the fuse

Chevy avalanche 07 doesn't want to go in the drive

Well iv changed a transmission and it still did not fix the problem and I’m still stuck on it changed 2 of the 4 sensors in the transmission I’m stupied for not changing the other 2 but I was kinda broke at the moment but yeah if any one can figure this out please let me know

It needs a new transmission

Hey You guys i Have a 202 Gmc Yukon Xl Just Bought it About 4 month Ago Drove well unntil About 3 months ago it shifts into 1st gear but when I get to 2nd and 3rd 4th gear it does not shift It's just rev un till I let off gass then it Shits to 3rd gear I really help Is notifying the problem

It's the valve stems of the transmission they are sticking

bad 3-4 clutch pack

Abs speed sensor. Transmission speed sensor w/e

Did you change both fuse

Body control module

That's not a 6.0l truck

Don't buy used, get that one rebuilt.

At 6:38 you replace it in the wrong spot right? Earlier you took the fuse out the was next to gray fuses. Then you took out the fuse and replace it in the wrong spot according to your diagram. I just want to make sure you're seeing what I'm seeing. Cheers.

Ever find the problem man

Speed sensor

you need to change your fluid

Change out the trans solenoids...that's your problem

Did u find out what the problem was

Replace the solenoids on the transaction

What fixed the issues
